Specifications

Description

The ABB DP620 3BHE300016R1 is a high-speed pulse counter module designed for industrial automation systems. It features multi-channel input processing capabilities and precise timing functions, making it suitable for industrial applications requiring high-precision position detection and speed control.

Applications

Large thermal power plants (steam turbine/auxiliary equipment control):

Analysis: Used to monitor turbine speed or precise feedwater pump flow (via turbine flow meter pulses). Its high-frequency response ensures millisecond-level triggering of overspeed protection logic.

Steel and metallurgical plants (plate rolling):

Analysis: Connects to encoders on the rolling mill roller conveyor to accurately measure steel plate length or control the synchronous position of the shearing machine. In high-speed rolling, the counting accuracy of the DP620 directly affects the product dimensional compliance rate.

Paper and printing plants:

Analysis: Manages the linear speed synchronization of the paper conveyor to prevent uneven paper tension from causing breakage.

Features

1.Basic Functions

High-speed counting capability:Supports single-phase 6-point(50kHz input each)or 2-phase 3-channel(15kHz input each)high-speed pulse counting.

Multi-mode input:Configurable to 4-point independent control 2-channel mode,with each input frequency up to 50kHz.

Wide frequency range:Supports an input frequency range of 6Hz to 4.8kHz,adaptable to different application scenarios.

Total 8 points:Integrates 8 input points,all equipped with high-speed counter functions.

2.Precise timing function

Multi-level timing accuracy:

0.5ms unit:Timing range 0.5ms to 1.5s,suitable for high-speed response scenarios.

10ms unit:Timing range 10ms to 30s,suitable for conventional control applications.

Flexible timing configuration:Supports 8 independent programs(6 programs only for C10 input).

Pulse consistency:Provides 4 programs to ensure the accuracy and stability of the pulse signal.

3.System Integration Capabilities

Communication Interface:As an FBP bus adapter module,it integrates a neutral bus interface function to achieve efficient communication with the CPU.

Distributed Expansion:Can be centrally expanded to include up to 7 input/output modules(up to 4 analog modules).

Compatibility:Perfectly compatible with ABB System 800xA and other industrial automation systems,supporting seamless system integration.

FAQ

Q1: Can the DP620 3BHE300016R1 connect to a 24V encoder?
A: Yes. It is generally compatible with standard 24V HTL level signals, but the input current-limiting resistor configuration must be checked against the manual.

Q2: Does DP620 3BHE300016R1 support hot-swapping?
A: Hot-swapping is strictly prohibited. To protect the S600 bus communication chip, the rack power must be disconnected before replacement.

Q3: Why is my count value always zero, but the field encoder is rotating about DP620 3BHE300016R1?
A: Check if the module's L+ external power supply is in place, or if the encoder's A/B phases are reversed/short-circuited.

Q4: Can DP620 3BHE300016R1 measure speed and cumulative position simultaneously?
A: Yes. In AC450 engineering software (such as AMPL), frequency (speed) and counter (position) values ​​can be read simultaneously.

Q5: What is its maximum input frequency about DP620 3BHE300016R1?
A: Typically supports pulse frequencies up to 50kHz - 100kHz, much higher than ordinary DI modules.
